Doug Shelton the head of corporate PR claims those numbers are off by a factor of 10+ and at the same time they opened up 15k new positions. They have 435,000 employees right now in total. Mind you a really significant number of those people are IBM Global Services which will constantly have people quitting and joining due to contracts.
I have 30 TB of Movies (Ripped via x264 @ 2.5GB/hr - 1080p) - I have the data stored on my NAS using zfs and I am seeing about a 35% savings. Now that's a LOT of savings to go down to 20TB. My NAS has plenty of space though since I have 45x3TB of disks.
Let's say that the rebuiilds CAN cause additional failures, not that it *often* does. I've done maybe 500-600 RAID5 rebuilds and only had two times that there were additional failures, both with consumer SATA/EIDE drives.
Most of the RAID failures I've seen have been due to no monitoring and having failed drives for months or even years.
The only electronics in the front are the lights, some sensors and the power steering stuff. Everything else is in the back. The front wheels seem undamaged, so nothing there. I'd think most likely it was either something on the floor (they have a Lexus, which could have leaked and tada oil fire.)
Definitely not SQL injection hacks, but poor PHP code can result in a root level RCE. It's mostly rare now-a-days though since most PHP is run in a userlimited or nobody fashion even if the code is bad, it can only affect the "site". None the less the number of "consumer" bots has always WAAAAAY exceeded the number of servers - actually probably the number of physical servers that exist in total.
